i got this b18a1 block yesterday and i opened it up to notice that all the rod bolts where only hand tight. so i removed the rods and this is what i found. scary music cue....







so i dont think he spun a bearing? why does it look like it does and what does it mean? cause that would mean the bearing moved right? and all 4 rods and bearings look like that but the mains look fine.

p.s sorry for all the Qs just need to know your expertise

f-in idiot people amaze me

 

looks like they got starved for oil/too hot.

 

x2

 

Damn your hands are scary!
looks like it ran too hot from the blue/purple marks, but the grinding seems to be from oil starvation.

 

bearing is in stage of spunning

 

Lol thx my hands are alittle scary lol. So it would have been caused by

Ls oil pump not enough oil after 7k

Oil leak

?

Wtf did he do to the poor thing. I should get a new crank huh

 

lack of oil --> spun bearings, can be from over revving as well

 

Well since the rod bolts where just hand tight, I would say the the clearance was to big and the oil pushed out of the journals to fast and easy (internal oil leak) so it just didn't get proper oiling and was getting hot. It's not real smashed out so I would think that the cranks rod journals are still round and usable, I would check all the rod journals on the crank with mic's just to be sure. Check the rods them selfs too and if all good get new bearings, torque them to spec and go for round 2 and have fun.

 

Ok yea that makes sense. Well I guess ill get everything checked out.
Thank you guys so much

Let this be a lesson everyone torque there bolts lol

 

Yeah, they're hot but when you see a really starved engine you'll see that the bearings are welded to the crank. Here is just looks like the bearings are shot. Pictures of the crank?

 

laffed

 

here ya go

 

so you guys think the cranks salvagable?

 

The far left journal looks questionable by looking, but hard to tell w/o feeling it. if you end up needing a LS crank i have a fresh micro-polished one for sale pm me.

I would get it to a machine shop and see what they say. If you have to take off the hard nickel-chrome coating from the journal i wouldnt use it. The tolerances will be loose and can cause rod slop/knock.

 

I would at least take it to the machine shop and let them check it as well, may just need to be polished back up. If u run ur finger over then journals and feel any indents then it maybe scrap. U could have it resurfaced and just use over sized bearings, I have had success with that but totally up to u.

 

Looks to me it was caused by insufficient lubrication, whatever the reason.. Low oil,beating on the engine, weak oil pump, diluted/dirty oil. The discoloration is from heat, another result of insufficient lubrication...
If that engine had been run with the rod bolts ONLY finger tight, I believe it would have blown almost immediately...
That leads me to believe the seller knew there was an issue with the engine. Sounds like they pulled the engine and checked the bearings,realized what they had, and threw it back together.. Did it look like someone was recently in there? Hope they were straight up with you...

Get everything thoroughly checked by a machine shop. Probably have to get the rods re-sized and the crank journals polished if there not damaged.

 

you know i didnt want to say but i got screwed on a trade lol but w.e its cool karmas a bitch.the good thing is its only a b18a1 which are a dime a dozen. it was meant to be in my hands anyways it has been bored to 82mm with p73ao type r pistons rs machines i think. the blocks fresh otherwise.

p.s if anyone in the mass area does business with them stay away or call me so i can hang them buy there dam toes in my front yard. (two black kids that drive a beat up ek 4 door baby blue) numbers are 781-325-2501 and 781-589-8556

 

****ing scammers.... facepalm...

 

wtf is spunning

 

lol and yea i got scammed with a gsr motor from a asian dude in jersey good thing is i traded the block for a turbo but bad thing is thats how i found out it was bad the dude i traded said it was knocking like crazy i didnt have the chance to check it out when i had it thats why now i dont even bother buying or trading with anyone who has a honda motor that says its built or rebuilt if its been touch i wont bother with it because 75 percent of honda folks are scamming you its sad really but true

 

Yea dude it sucks in this game of hondas you got scammers and theives to worry about....f**k it right that's life I guess lol

 

You just gotta inspect everything really carefully before closing the deal...
Anytime I buy something used, I bring some tools along to check or measure it.
Cams,cranks,whatever...A few minutes with a micrometer can save you alot of money.

 

thanks guys i appreciate the help and the words of wisedom.i guess you dont realize how the world is sometimes lol
thanks

 

So I have these pics of the journals these are the worst ones ar they useable still when you brush your finger over the journals you can't feel any grooves or scratches

 

i would get the crank check and cleaned and go from there
